Abstract (en)

[origin: WO2009143859A1] The invention relates to an apparatus and a method for renegotiating a multimedia connection as well as to an associated communication system, a digital storage medium, a computer program product and a computer program, wherein a first signalling operation with public network addresses (wna1, wna2) and public port addresses (wpa1, wpa2) is first of all carried out. A predetermined waiting time (T) is started and a multimedia connection set-up is detected. If a multimedia connection could not be set up after the predetermined waiting time (T=O) has elapsed, a second signalling operation is carried out using at least one private network address (lna1).
